Occupy Philadelphia and Occupy Oakland, Papillomavirus and Vaccination, Endangered Kentucky Mussel: Today on Here and Now

1:06pm: As winter approaches, there’s been a wide range of reactions from municipal leaders to the Occupy Wall Street protestors in their cities. In Philadelphia, the city and protesters are headed for their first major confrontation since the demonstration began there three weeks ago. Protesters have set up hundreds of tents outside of City Hall in Dilworth Plaza, and city officials are suggesting the group pull up stakes and move across the street to allow a planned $50-million construction project to go forward. The city also says the demonstrators aren’t acting fast enough to deal with sanitation concerns.

1:12pm: The mayor of Oakland, Calif. is promising a “light police presence” for the next few days after officers used tear gas to break up protestors there on Tuesday.

1:21pm: An astronomical rise in throat and neck cancers in men is blamed on the HPV virus which also causes cervical cancer in women. In fact, some researchers say these cancers in men may outnumber the cases of cervical cancer within a decade. Infection with virus, which is spread primarily through sexual contact, can be prevented through vaccination and an advisory committee for the Centers for Disease Control is recommending vaccination for 11 and 12-year-old boys, as well as girls.

1:35: Tigers, grizzly bears, sea turtles and humpback whales have long been mascots of endangered species. But then…there’s the pink mucket mussel, which once peppered river bottoms in Kentucky, but has since been decimated by pollution. Now, scientists are now hoping to re-establish healthy populations of the mussels. Kentucky Public Radio’s Erica Peterson went along with a team to the Green River.
